discuss solution to snapshot problem

Possible alternatives:
1. Backtracing data from the chain
2. Implement views in the smart contract
3. Implement events and emit them in the correct function calls,

My recommendation is adding event to popular external trxs. For demend like statistics for rank of deposit amount, it's hard to get information by some view in vault contract since vault token is tokenized as currency asset and extra storage space will be needed for tracing that. Instead with well-designed event, we can not only do statistics to support business operations, but make internal status in trxs observable, which is useful for tests.

Agreed, let's do this. Thanks for the advice!
